Penta midrange wiring.

Hi Guys,

Does it matter which way round these orange wires are? ie could I have p19 in p20s place or vice versa at the crossover end.... 

 

Lee, from an electrical point of view they would both link back to the same voltage level so if you had them crossed over it would not make a difference.

Hi Gavin,

would it make an audible difference?

I guess if it doesn't electrically it won't make any difference sonically.

I'm not an electrician etc but would go out on a limb and say it may make a difference. If they are swapped, the signal illustrated to the top speaker (labeled midrange) will go via a different route of capacitors etc. that's presumably for a reason? Will it change the signals to the midrange and hence the sound?

I guess you didn't label them during some work? Been there, done that myself!

If it mattered in the slightest, they wouldn't both be orange. Think of production costs and the poor assembly line worker.

A very good point Mika.  Try them both ways and listen to see if there is a difference.  I know there are times when the wire colour is important (do I cut the red wire of the blue wire? BANG!) in this case you may well be right.

It doesn't matter the slightest.
Two orange wires coming from the same connection.
How did B&O tell them apart when the speaker was put together? - They didn't.

Definitive as always Martin. Good to know. The same can't be said of all vintage manufacturers though. My classic Lotus Elan Sprint has the same color wires for nearly everything and it's a very complicated loom. You have to trace each and every wire to make sure it's all OK. You can see why I Was a Biologist and not an electrician!

In electrical way of thinking it could have something to do with the amount of current through the wiring. (which is not the case here). The sum of both currents in both leads could be to much for just one lead. But again, that's not the case here.

For the ones who think the mids looks a bit odd drawed, there is a explanation for it. The way they are drawed in this diagram is the actual way they are fitted in the mid section. Be aware and look carefully that the 2 short orange wires, which connected to the mids. Be sure that you connect them correct with the positive lead from one mid connected to the other negative lead.

Also looking at the wiring diagram is the tweeter out of phase?

Lee

Nop, in phase. Electrically wired the oppossite way you might think, but it's in phase. Components like capacitors and inductors causes phase-shift.

If you don't take L4 and L5 into account, then C4 and C5 only causes 180dgr phase-shift. Connecting the tweeter the "wrong" way causes again another 180dgr shift. Total then is 360dgr, which is in phase...
